Just checking. Windoze tools don't generally do the right thing for cygwin's emulation of posix perms.

Apart from that, the file permission settings are the same in Vista
compared to older OSes.  The exception is the UAC stuff which could
result in some executables having less permissions than usual, if, for
instance, Internet Explorer has been used to download the executable.
We can hopefully rule this out here, so it's just some permission
problem which has nothing to do with the base OS.

I want to throw an AYS in Corinna's general direction here... one of the
ongoing problems in 'doze security since waaaay back when is that the default
perms for user-created files, the equivalent of the default umask under posix,
have always been pretty wide open: AYS they haven't been tightened up for

Works fine on XP. The only things that are diferent are the Cygwin
instillation and Vista.

Heh, so that's a bit like saying "The only things that are different are everything, apart from the gcc source code".

Unmodified GCC 4.2.0 compiles okay, but when modified cracks appear, only on
Vista though, XP is okay. So must be something to do with permissions.

So, what tool did you use to 'modify' it?

A Windows text editor called Zeus.

I have been altering the C source code and some configureation and gcc/makefile but AFAICT nothing that should effect gcc/configure though.

Its all very odd.

Hopefully I shall get to the bottom of it if I perservere, but any help or suggestions are welcome.
